dotu (USM Version)¶
Computes the dot product of two complex vectors.
API¶
Syntax¶
namespace oneapi::mkl::blas {
event dotu(queue &exec_queue,
std::int64_t n,
const T *x,
std::int64_t incx,
const T *y,
std::int64_t incy,
T *result,
const vector_class<event> &dependencies = {})
}
The USM version of dotu
supports the following precisions and devices.

Input Parameters¶
- exec_queue
The queue where the routine should be executed.
- n
Number of elements in vectors
x
andy
.- x
Pointer to the input vector
x
. The array holding input vectorx
must be of size at least (1 + (n
- 1)*abs(incx
)). See Matrix Storage for more details.- incx
Stride of vector x.
- y
Pointer to input vector
y
. The array holding input vectory
must be of size at least (1 + (n
- 1)*abs(incy
)). See Matrix Storage for more details.- incy
Stride of vector y.
- dependencies
List of events to wait for before starting computation, if any. If omitted, defaults to no dependencies.
Output Parameters¶
- result
Pointer to where the result (a scalar) is stored.
Return Values¶
Output event to wait on to ensure computation is complete.
